Title: Pipe lap joint with improved collapsible sealing zone
Inventor: AMEDURE MICHAEL E
IPC: F16L25/10
Filed: 1995-12-19
Abstract: A pipe lap joint is disclosed with an improved sealing zone and which comprises a pair of end-to-end intersecting slots in the outer pipe which allow the sealing zone to be collapsed against the inner pipe by a band clamp around the outer pipe. The outboard slot extends inwardly from the end of the pipe and the inboard slot is circumferentially offset and extends inwardly from the outboard slot. A frangible bridging segment of the wall of the pipe extends between the adjacent walls of the two slots and is deformed or fractured and maintains isolation between the slots when the pipe is collapsed. To facilitate collapse of the outer pipe, the length of the inboard slot is maximized for increased leverage of the clamping force.

Title: Process and device for recovering amines and use of residues obtainable thereby
Inventor: GIEBELER EBERHARD
IPC: B01D3/00
Filed: 1995-05-03
Abstract: The invention relates to a process for recovering amines from acid amine salt solutions by the addition of bases and evaporating the solution at a pH of 11 to 13 in a kneading drier until a useful solid is obtained as the distillation residue and a device for separating sludges and suspensions into a solid and a plurality of liquid fractions separated according to their boiling point.  The low-water-content amine phase separated out by distillation is dehydrated with calcium oxide or potassium hydroxide and then separated into pure amine fractions by rectification.  The process described makes it possible to utilise all the secondary flows and completely recycle the amines and the absorption medium (sulphuric acid).  The flows for the recycling process are amine-charged washing acids from absorbers obtained from the cleaning of amine-containing exhaust gases obtained, produced for instance in the cold box process for hardening core sand in foundries.

Title: Microcell load measurement using feedback control
Inventor: LEE DAVID Y
IPC: H04B7/26
Filed: 1997-11-18
Abstract: A method and system are disclosed for determining load on a microcell in a telecommunications network. The network comprises a base station, at least one microcell controlled by the base station, at least one terminal served by the mi crocell, and feedback between the base station and the terminal. The feedback enables the terminal to provide an up-link signal indicative of a particular down-link signa l from the microcell. The method embodiment of the invention involves transmitting a partic ular down-link signal from the microcell, and receiving an up-link signal from a term inal. Next, a determination is made whether the up-link signal is indicative of the pa rticular down-link signal. If it is, then the load on the microcell includes the terminal . The method and system are particularly useful in CATV networks having a plurality of microcells operating in a simulcast mode. In one preferred embodiment, the micro cell transmits the particular down-link signal in a certain pattern, if the up-link s ignals of the terminal reflect the pattern of the particular down-link signal, then its load o n the microcell is confirmed. Once the load of a microcell is determined, then the net work may be optimized for capacity and quality. In one embodiment, optimization is performed by altering the RF carrier among the microcells to balance load in the network.
